Bicycle tire tread



FIG. 1 is a perspective view of a bicycle tire tread showing my new design, it being understood that the pattern which is partially illustrated is repeated uniformly throughout the circumference of the tread as shown schematically in solid lines;

FIG. 2 is an enlarged fragmentary plan view showing the tread pattern in greater detail; and

FIG. 3 is a transverse section taken substantially along the line 3--3 of FIG. 2 illustrating the profile of the tread pattern in greater detail.

The broken line showing of the tire carcase in FIGS. 1 and 3 is for illustrative purposes only and forms no part of the design. 

The ornamental design for a bicycle tire tread, as shown and described.
